Vitreous and porcelain enamels - Release from enamelled articles in contact with food - Methods of test and limits
Also Known As:
A standard called ISO 4531 describes how to test for and define limits for the release of metal ions from enameled objects in contact with food. The standard encompasses tanks, vessels, and other items used for food preparation, cooking, serving, and storage, as well as a simulation method for testing the release of metal ions from enameled ware.
The testing procedure outlined in ISO 4531 is intended to simulate the circumstances that enameled objects would experience while coming into contact with food. This includes heating the items, treating them with acids and alkalis, and exposing them to liquids that mimic food. In order to ensure that any potential migration into the food does not go over acceptable levels, the standard also establishes allowed limits for the release of metal ions.
The safety and caliber of enameled items used in food contact applications are ensured in part by ISO 4531. The standard serves to safeguard consumers from potential health concerns related to the release of metal-ions from these items by establishing testing procedures and limits. Manufacturers must demonstrate that their enameled ware is safe for use with food by complying with ISO 4531 in order to give customers confidence in the goods they purchase.
